Hi, I also have a puppy with kennel cough. I took her to the vet and explained my concerns and she told me that I had nothing to worry about, my ferrets could not catch it from the puppy. Just another bit of info. Our pup was given Doxycycline for her Kennel Cough and it did not help. She is now on a dose of Amoxi and it has done the trick.
